Full VMs with systemd and a real kernel — on your Mac, your servers, or your cloud.
Build and run untrusted code, background jobs, preview environments, autoscaling infrastructure, and sandboxes.
Run untrusted code with the ease of containers, but a full guest Kernel, OS and systemd.
Securely inject secrets and credentials into microVMs from the host.
Program Linux systems with slicer's guest agent for cp, exec, shell, metrics, and port-forwarding.
Mount PCI devices like GPUs, TPUs, and NICs into microVMs for hardware acceleration.
Run automated bots for code reviews, notifications, and integrations. See our code review bot built with opencode.
microVMs are better suited for processing large media files. See example.
Files are shared directly via VSOCK — no network round-trips to a remote API. Your data never leaves your machine.
Launch Kubernetes nodes via API with node scaling and termination.
Every microVM runs a real kernel with systemd, package managers, and cron. Run Kubernetes clusters, pass through GPUs, or replace your entire dev VM stack — on the same platform.
Stop waiting for cloud access, VPN approvals, or AWS accounts. Every developer gets real Linux with systemd on their laptop — same packages, same tooling, same workflows as production.
No AWS accounts, no EKS clusters, no cloud VMs. Real Linux runs locally on the hardware your team already has.
A developer expenses $25/mo. No security review, no vendor assessment, no data leaving the building.
Ubuntu LTS and Rocky Linux with systemd — the same OS you run in production. Not a macOS approximation.
One tool instead of Docker Desktop, Colima, Lima, or UTM. Sandboxes and services from the same product.
Run persistent workloads on cost-effective bare-metal instead of expensive cloud instances. Homelabs, Kubernetes, dev environments, and customer support — all with systemd and a full OS.
One of the fastest ways to spin up HA Kubernetes clusters for development, testing, and demos.
Run on your own bare-metal hardware at a fraction of cloud costs. No more unhinged cloud spend for dev and test environments.
Boot a Debian- or RHEL-like OS with systemd, matching your production environment.
Slicer's base images are OCI images. Extend them with a Dockerfile — add packages, tooling, or your own software in a single build step.
From customer support to product testing to full Kubernetes clusters — real workflows on real Linux, not cloud simulations.
Reproduce a customer's issue on their exact OS. Boot a fresh Ubuntu or Rocky environment, debug, ship the fix — all in minutes.
Build, test, and iterate locally with VSOCK I/O — no pushing to a remote server. Tear down and rebuild in under a second.
Spin up multi-node clusters with real networking and autoscaling nodes. Simulate real cloud infrastructure on a single bare-metal host.
Test against Ubuntu LTS and Rocky Linux (RHEL-compatible) on x86_64 and arm64. Ship with confidence to enterprise and airgapped environments.
Slicer's code has run 3M+ CI minutes on Arm runners for CNCF — securing the ecosystem before it hit GitHub's roadmap.
Alex Ellis, founder of OpenFaaS: We've run Slicer internally since 2022 which has kept our cloud costs really low and given us the fastest response times we've seen yet on customer support tickets.
Start with a 14-day free trial. No security review needed — it runs on your machine.
